My great-grandmother's maiden name was Ekaterina Mikhailovna Nikolaevna. She was born in Ostashkov, near Kiev, Ukraine. Her mother was Irina Semonovna. From what I can tell, both Nikolaev and Semonov are common Russian surnames.

My great-grandmother and her 2nd husband, Arseny Vlasoff lived in Tientsin (now Tianjin) from about 1921 to 1949. In 1949 they fled the communist advances and went to Shanghai to catch a ship to Tubabao, Philippines. They were Displaced Persons there until 1951 when the US allowed them and a couple thousand others from Russia to come in to the country.

It is unknown what happened to her first husband, my grandmother's father, Ivan Petrovich Plasovsky. My grandmother last saw him in 1928. It was presumed that he returend to the Soviet Union.

I would be happy to hear if there is other family still in Russia.
